Ingredients
- Butter: melted butter creates a chewy brownie texture and rich flavor choose unsalted for best control
- Semi sweet or dark chocolate chips: melt some for the batter and stir in extra for gooey bites select a good quality chocolate for deep flavor
- Light brown sugar: brings moisture and a molasses hint always pack it when measuring
- Vanilla extract: rounds out chocolate and peanut butter flavors real vanilla makes a difference
- Eggs: bind everything together and give brownies structure use large eggs at room temperature if possible
- All purpose flour: ensures the right lift spoon and level for accuracy
- Kosher salt: balances sweetness and brings out chocolate notes look for fine grains that dissolve easily
- Cream cheese: for the frosting adds tang and stability to help the peanut butter set smoothly let it warm to room temperature for easy mixing
- More butter: in the frosting keeps it creamy and spreadable
- Creamy peanut butter: provides that classic nutty flavor stick with a creamy variety for the smoothest results
- Powdered sugar: sweetens and thickens the frosting sift if lumpy
- Heavy cream or milk: ensures the frosting is soft and easy to spread add gradually as needed
Step by Step Instructions
- Prepare the Brownie Batter:
- Melt the butter in a large saucepan over medium heat and then add most of the chocolate chips stirring until they are smooth and glossy This sets a rich chocolate base that needs no mixer
- Combine the Wet Ingredients:
- After removing from heat stir in the brown sugar and vanilla then whisk in eggs one at a time until fully combined A shiny batter means you are building fudgy layers
- Add Dry Ingredients and Mix Ins:
- Slowly fold in the flour and salt until just combined Overmixing can make brownies tough so stop when you see only a few streaks Add in the rest of the chocolate chips for melty pockets in every bite
- Bake the Brownies:
- Spread the batter into your lined pan and bake for just under half an hour Test with a toothpick it should come out with moist crumbs not wet batter Cool completely before frosting so the topping does not melt
- Make the Peanut Butter Frosting:
- Beat cream cheese butter and peanut butter together until creamy and fluffy Starting with room temperature ingredients helps create a smooth base Mix in the powdered sugar until thick then add cream or milk one tablespoon at a time until the texture is spreadable
- Frost and Chill:
- Gently spread the peanut butter frosting over the cooled brownies making sure to get all the way to the edges Chill for one to two hours so the frosting firms up making the bars easy to slice Store any extras in the fridge or freezer
